DUMP-CAR DOOR.

Specification of Letters Patent.

Patented Mar. 10, 1914.

Application mea April 1s, 1912'. serial No. 690,571.

To all whom it may concern:

Be it known that I, RICHARD WEBB BUR- NETT, a citizen of the United States v of America, residing 'at the city of Montreal, in the Provincev of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Dump-Car Doors; and I do hereby declare that 'the following is a full,clear, and exact description thereof.

My invention relates particularly to the means whereby the dump doors of dump cars are sealed and it has for its object' to increase the sealing qualities of the joints between the side edges of the doors and the door frames without the necessity of altering the construction of the usual flanged door opening.

The invention may be said briefly to consist of pockets formed at the side edges-of a dump door and adapted to receive the side flanges of the door opening and form an effective seal between such parts. For full comprehension, however,H of my invention reference must be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate the same parts, and wherein:

Figure 1 is an enlarged detail sectional perspective view of the meeting edges of the door and door frame taken on line A A Fig. 2; and Fi 2 is a transverse .vertical sectional view o a ortion of the floor structure of hopper ormation of a grain car having a door provided with my invention.

I have illustrated my invention applied to a type of a hopper band door c in which the door is when closed in ,a nearly vertical lane but I do not claim this structure as -it orms the subject-matter of a separate application filed by me on October 17, 1911, under Serial No. 655,253.

According to my present invention the door is of trough form the side flanges being indicated at d and pockets are formed at the side edges 'by angular plates e, the horizontal legs of which are riveted as at f to the bottom of the door while the angular plate extends from end to end of the latter. As the member e is attached outside of the flange d it affords no obstruction to the discharge of the lading.

What I claim is as follows In a car for loose commodities a discharge hopper having walls with straight side edges, and a door hinged at one `edge to the hopper and having side flanges with pockets having flared mouths and said pockets being adapted to envelop and closely lit theside edges of the walls when the door is closed.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.

RICHARD WEBB BURNETT.
